-This invention relates to new and useful improvements in telephoneattachments and has for its principal object to provide a flevice whichis designed to eliminate waste of current from the batteries used inconnection withthe telephone.

Another object of the invention is to pro v/igjle anieans for cuttingout the. battery cir-` cuit entirely and connecting the line so as toprevent interference with other telephones.

Still another object of the invention' is to provide a switch forlocatinga dead -box in the line which will eliminate much time aiidtrouble which is usually necessitated in the ordinary systems when aswitclrof this character is not used.

further object ot' this invention is to provide a switch of the aboveclass which eliminates the necessity ot' holdingthe switch in Contactwithout inconveiiiencing the user. 1

A still further object ,of the invention is transmitter circuitinoperative and still enable the listening circuit to he cut in,'thuspermitting the listener on the4 line to hear without interfering withthe parties talliing and relieves any stress on the batteries 'of thetelephone. y i l `W ith these and other objects in view, the inventionconsists in the novel ciiinbination and arrangement ot parts which willbe `t'ully set torth in the following specification and accompanyingdrawing, in which,

This button A12 comprisestlie.liaiidle portion il which inay be of any suitable material and thishandle portion has projectiiig' from the base there'ot` the tubularextension 1l which terminatcsat its inner end in the flange l5, whichflange is arranged to lie in the cutaway portion l1 and prevent thebutton troni hein,Y displaced. ,Projecting' inwardly t'roni each ottheplates 7 and 3 are the extensions '1G carrying at their outer endsthe binding pos't 17 to which the wires 1S are secured.

lt will be. apparent from the foregoing that in use` the plates 7 and Sare secured to the teleplioiiein any suitable manner so the tubularmembers 1G project nccted respectively in circuit with the batterycircuit so-that the plates will torni a break therein unless the buttonpushed so as to 'torni a contact therebetween. It will thus be seen thata considerable saving in the, batteryis ettected'due to the fart thatshould a. person lift the receiver from the hook when they listenr overthe line, unless the button 12 is pushed into the proper position, anytransmisionfrom that particular ln view of this fact it will be clearlyseen that considerable saving will be elt'erted and-any leali or wasteof current troni the battery prevented.

While in the foregoing there has been `shown and described the preferredem bodime'nt ot this invention, it is to be understood that such changesmay be made in the and a retaining plate at one end of the first namedplates and provided with a slot alined with the groove formed by thefirst named plates, said slot of the last named plate being arranged toreceive the button therein ho-ding the same out of contact position. s

In testirnon)7 whereof I affix my signature in presence of twowitnesses.
